Notes
-s’eh/-zeh “ten”. In compound numbers (e.g. tăs’eh–hnăs’eh– thoùn-zeh) -s’eh is voiced to -zeh except after a syllable ending in -q or in -ă. Changing the pronunciation from s’ to z is known as “voicing”. For more see “Voicing Rule” in Appendix 1.
t iq/t ă- “one”. When the numbers t iq, hniq, k’un-hniq are combined with s’eh, they are shortened, so instead of tiq-s’eh, hniq-s’eh, k’un-hniq-s’eh you hear: tăs’eh, hnăs’eh, k’un-năs’eh. We call this change from t iq to tă etc “weakening”. It takes place when tiq, hniq, k’un-hniq are combined with any other word: tăs’eh “one ten”, hnăya “two hundreds”, k’un-năt’aun “seven thousands”, tăk’weq “one cup”, and so on.
